“…Araújo et al [60] published a retrospective study on patients who received zygomatic implants between 2007 and 2014. A total of 129 zygomatic implants were placed by the Stella and Warner [4] (sinusslot) technique in two surgical times (without immediate loading).…”

The objective of the present chapter is to present a time-line of the zygomatic implant technique. A literature review was performed to find relevant studies and to put them in chronological order to obtain a general perspective of the advances and evolution of the technique. The two major changes occurred from the development of the technique by professor P.I. Branemark in 1989 and its introduction to dental profession in 1998 were the surgical technique, itself, and the use of immediate loading protocols. In regard the surgical technique, a paradigm shift was developed changing the zigomatic implant insertion from an intrasinus to an extrasinus path, allowing an easier and less morbid procedure. The introduction of immediate loading entails a dramatic shortening of treatment time for the patiens in their seek of a functional prosthesis, getting the same or better results than the original two-step procedure.

“…These data allowed the authors to affirm that for the two groups of individuals studied, the anesthetic protocols did not have an influence on satisfaction, showing that it was possible to perform the surgical procedure in hospital under general anesthesia, or in the outpatient clinic with local anesthesia and sedation [16] . This is an important datum for surgeries, considering that with the appearance of new zygomatic implant placement techniques - the exteriorized and extramaxillary types [16] , [18] , [19] , in which the zygomatic implants pass outside the maxillary sinus, the surgical time is reduced, allowing the surgical procedure to be performed in an outpatient clinic with local anesthesia and sedation, for both immediate and late loading [20] , [21] . For the individuals, having the procedure performed in an outpatient clinic reduces financial expenditure on hospital intervention, in addition to being able to go home soon after surgery is concluded, provided they are operated on by experienced professionals [16] .…”

PurposeTo evaluate the satisfaction of individuals with atrophic maxilla, rehabilitated with fixed dental prostheses, anchored on zygomatic implants, with variables being the anesthetic procedure: general anesthesia, or local with sedation.Materials and MethodsBy means of the clinical record charts from the Training Course in Advanced Hospital Surgeries for Implant Dentists conducted at the Campinas-SP unit of the São Leopoldo Mandic School of Dentistry, 30 individuals were randomly selected. They had zygomatic implant placement surgeries performed, and were rehabilitated with fixed implant supported complete dentures, between the years 2005 and 2011. One group of 15 individuals underwent surgery in hospital, under general anesthesia. The other 15 were treated in the post-graduation clinic at the School of Dentistry, under local anesthesia and sedation.ResultsFrom the emotional point of view, the Wilcoxon test revealed that irrespective of the anesthesia procedure used, at the beginning of treatment, the emotional condition of individuals differed from that verified after conclusion of the treatment (p < 0.0001).ConclusionThere was no difference between the two groups as regards the anesthetic procedure. General satisfaction was high; there was emotional improvement after conclusion of the treatment, thus improving the quality of life.

The aim of this systematic review and meta-analysis was to analyze and compare the survival rate and prosthetic and sinus complications of zygomatic dental implants for the rehabilitation of the atrophic edentulous maxilla. Materials and methods: We conducted a systematic literature review and meta-analysis, based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations, of clinical studies that evaluated the survival rate and prosthetic and sinus complications of zygomatic dental implants for the rehabilitation of the atrophic edentulous maxilla. Four databases were consulted during the literature search: Pubmed–Medline, Scopus, Embase, and Web of Science. After eliminating duplicate articles and applying the inclusion criteria, 46 articles were selected for the qualitative analysis and 32 for the quantitative analysis. Results: Four randomized controlled trials, 19 prospective clinical studies, 20 retrospective studies, and 3 case series were included in the meta-analysis. Conventional dental implants failure (n = 3549) were seen in 2.89% (IC-95% 1.83–3.96%), while zygomatic dental implants failure (n = 1895) were seen in 0.69% (IC-95% 0.21–1.16%). The measure of the effect size used was the Odds Ratio, which was estimated at 2.05 with a confidence interval of 95% between 1.22 and 3.44 (z test = 2.73; p-value = 0.006). The failure risk of conventional dental implants is 2.1 times higher than that of zygomatic dental implants. Slight heterogeneity was determined in the meta-analysis between 23 combined studies (Q test = 32.4; p-value = 0.070; I2 = 32.1%). Prosthetic complications were recorded in 4.9% (IC-95% 2.7–7.3%) and mild heterogeneity was observed in a meta-analysis of 28 combined studies (Q test = 88.2; p-value = 0.001; I2 = 69.4%). Sinus complications were seen in 4.7% (IC-95% 2.8–6.5%) and mild heterogeneity was observed in a meta-analysis of 32 combined studies (Q test = 75.3; p-value = 0.001; I2 = 58.8%). Conclusions: The high survival rate and low prosthetic and sinus complications related to zygomatic dental implants suggest the use of zygomatic dental implants for the rehabilitation of the atrophic edentulous maxilla.
